FIG. 2 is a greatly enlarged, vertical sectional view through the foremost portion of the dispenser along the longitudinal axis thereof with the valve in open condition.

FIG. 3 is a greatly enlarged, front elevational view of one embodiment of dispenser head utilized in the practice of the invention.

FIG. 4 is a greatly enlarged, vertical sectional view along the longitudinal axis of another embodiment of dispenser head, showing the valve in closed condition.

FIG. 5 is a greatly enlarged, vertical sectional view along the longitudinal axis of the adapter of the invention.

FIG. 6 is a greatly enlarged, horizontal sectional view taken slightly above the plane of the lever of the adapter, looking downwardly.

Referring now to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in FIGS. 1 and 5 of the drawings a conventional pressurized container 10 including annular shoulder 11 in the upper end thereof which defines depression 12; upwardly extending bell portion 13 in the center of said depression accommodates dispensing valve 14 with stem 15 and vertical dispensing opening 16 extending above the plane of shoulder 11. In the pressurized container thus formed, stem 15 is normally biased upwardly as by a suitable spring; when said stem is depressed against the,

pressure of said spring, the material from container 10 flows through opening 16.

As best seen in FIG. 5 of the drawings, adapter 17 is detachably secured to shoulder 11 of container 10. More specifically, longitudinally extending body 18 terminates downwardly in ring 19 which defines recess 20; said ring is adapted topass intermediate annular shoulder 11 and bell portion 13. Male threads 21 are provided above ring 19 exteriorly of the lower portion of body 18; said threads terminate upwardly in proximity to collar 22 integrally formed with said body and slightly below the midpoint thereof. Nut 23, mating with threads 21, terminates downwardly in collar 24 of reduced diameter provided exteriorly with laterally extending arcuate member 25 adapted to pass downwardly and inwardly of shoulder 11 thereby engaging the same, and exteriorly in downwardly depending lip 26 adapted to frictionally engage the outer surface of ring 19.

Upwardly of collar 22, cylindrical section 27 of said body is of reduced diameter with integrally formed, laterally extending, generally U-shaped lugs 28-29 (see FIG. 6) in proximity to the upper end thereof. Vertically extending gussets 30 support the lower portion of said cylindrical section. Actuating lever 31 includes outwardly extending trunnions 32-33 adapted to insert into lugs 28-29 and essentially perpendicularly extending arm 34 the innermost end of which is provided with transversely extending teeth 35. Downwardly of trunnions 32,33 said lever includes an integrally formed, inwardly extending, arcuate spring 36 the lower end of which bears against cylindrical section 27. Longitudinally extending bore 37 in body 18 communicates upwardly with opening 38 in the top of said body.

Still referring to FIG. 5 of the drawings, sleeve 38 inserts into the lower portion of bore 37; said sleeve terminates downwardly in diverging conical section 40 the inner surface of which is adapted to bear against bell portion 13 with the lower edge of said conical section 40 normally lying in the plane of the lower edge of ring 19. As will hereinafter be described, ring 41 may be carriedon sleeve 39 whereby'said sleeve may be adjustably positioned within bore 37 to accommodate bell portion 13 of any height. Elongated valve 42 terminates downwardly in integrally formed anddiverging conical section 43; longitudinally extending tube 44 of metallic composition, adapted to insert into opening 16, is fixedly secured in valve 42. with the lower end thereof extending substantially downwardly of the lower edge of conical section 43. Spring 45, carried on valve 42, bears against the upper end of sleeve 39 and the lower end of collar 46 integrally formed in the approximate medial portion of said valve, respectively. Upwardly of collar 46, generally cylindrical section 47 of said valve is adapted to pass through opening 38.

As best'seen in FIG. 6 of the drawings, a plurality of longitudinally spaced teeth 48 are provided in section 47 intermediate lugs 28-29, said teeth are adapted to be engaged by teeth 35 on lever 31. The upper end of valve 42 is threaded and preferably beveled, indicated by reference numerals 49-50, respectively. One end of an elongated tube 51 of plastic composition is press fitted over bevel 50 and fixedlysecured thereto by means of nut 52 adjusted to bear against the outer surface thereof. The lower end of tube 44 is desirably provided with a diagonally and upwardly extending vent or recess 53; bore 54 of tube 44 communicates with bore 55 of corresponding diameter in said valve downwardly of collar 46 with coaxial bore 56 of greater diameter communicating therewith and surfacing in the top of said valve.

Referring now to FIGS. 1-4 of the drawings, there is shown a finger actuated dispenser 57'detachably secured to the remote end of elongated tube 51. More specifically, dispenser 57 includes a generally cylindrical forward section 58 which terminates rearwardly in male threads 59; rearwardly converging base 60 includes a longitudinally extending recess 61 in the foremost end thereof and female threads 62 adapted to engage threads 59. Valve 63 is adjustably mounted in longitudinally extending bore 64 in forward section 58.

Forwardly, bore 64 includes converging conical shoulder 65, communicating bore 66 of reduced diameter, converging shoulder 67, converging conical seat 68 paralleling shoulder 67 and rearwardly thereof, and axial bore 69 of still further reduced diameter. Valve 63 includes integrally formed, diverging conical section 70 the circumferential edge of which is adapted to expand against bore 64 in a tight fit when liquid under pressure is introduced into the said bore in a manner hereinafter to be described. Forwardly thereof, valve 63 includes a reduced diametral cylindrical section 71, and a still further reduced diametral cylindrical section 72 which terminates fowardly in converging conical face 73 adapted to bear against seat 68.

Exteriorly, forward section 58 terminates rearwardly in transversely spaced, U-shaped lugs 74-75 (lug 74 not shown) with recess 76 therebetween. Forwardly extending lever arm 77 includes trunnions 78-79 (trunnion 79 not shown) adapted to insert into lugs 74,75; essentially perpendicularly extending leg 80 of lever 77 inserts downwardly into recess 81 provided in valve 63. Spring 82 carried in recess 61 bears against the rear end of valve 63 maintaining the same in normally closed condition. Downwardly depending connector 83, integrally formed on forward section 58,includes male threads 84 and desirably is beveled, indicated by reference numeral 85. The remote end of tube 51 is press fitted onto bevel 85 and retained thereon by means of nut 86 adjusted to bear against the outer surface of said tube. Axial bore 87 in connector 83 communicated with bore 64 forwardly of the foremost limit of travel of valve 63.

Disc 88 terminates forwardly in transversely extending collar 89; female threaded portion 90, provided in the rear surface of said disc, is adapted to mate with threads 91 in the foremost end of section 58. Bore 92 in disc 88 communicates with bore 69 heretofore mentioned.

Rotatable disc 93 includes a plurality of integrally formed and rearwardly extending lugs 94 adapted to pass laterally of collar 89 with perpendicularly depending flanges 95 on each lug passing rearwardly of said collar. As viewed in FIG. 3, a plurality of nozzles 96-99 to provide sufficient spray patterns are press fitted or otherwise secured in disc 93 in such a manner that each of said nozzles is adapted to align with bore 92 in disc 88. Projections 100 on the rear surface of disc 93 insert into depressions 101 in the foremost surface of disc 88 for such alignment.

In the embodiment of FIG. 4, a single nozzle 102 of generally truncated conical configuration terminates rearwardly in female threads 103 adapted to engage threads 91 on section 58 with axial bore 104 in said nozzle communicating with bore 69.

In use, nut 23 is at least partially threaded onto threads 21 and collar 24 inserted intermediate shoulder 11 and bell portion 13; nut 23 is then rotated in such a direction that arcuate member 25 passes under and engages shoulder 11 of container 10, and conical section 40 bears against bell portion 13 of said container. A downward force on section 47 causes tube 44 to insert into opening 16 in stem 15. The user may conveniently grasp dispenser 57 with the fingers and apply a downward force on lever 77 whereby the material in container is dispensed through a selected nozzle.

Upon releasing lever 77, valve 63 returns to normally closed condition; upon depressing lever 31, spring 45 forces valve 42 upwardly whereby tube 44 is withdrawn from stem 15.
